Setting up Google Authenticator 1st Class Service

On return from a trip overseas when trying to login to my WP sites I got strange messages and found that the 2FA had been turned off. This appears to have been because the miniOrange authenticator I have used for many years has now been retired. I tried setting up Google Authenticator but was getting errors. I contacted support and after a couple of Google Meet sessions with Vikas he was able to talk me through some adjustments to the plugin settings and files and now all appears to work well. Thanks for quick and excellwnt support for a free product.
